hi there im new to keeping aphibians but am quite experienced with keeping many fish species and nature style planted tanks. I just bought the medium size Exo-Terra rainforest kit. Im always looking to make a beautiful natural enviroment. I was just wondering on how to make a great looking background with pots and then the bigger question; how do i make a waterfall like structure that flows from a top and then ends into a pool of water. Is this possible , and how do i get the water to circulate?!

Thanks!
